Virology

Pacific spadenose sharks are identified as hosts of the Flavivirus Wenzhou shark flavivirus.^[2] While currently unknown if Wenzhou shark flavivirus causes disease in infected shark hosts, it is thought that the virus moves horizontally from the gazami crab Portunus trituberculatus to shark hosts^[3] in a manner similar to other Flavivirus infections such as Dengue virus, which cycle horizontally between arthropod (mosquito) and vertebrate hosts.
